ENCLOSED GLASS HOLDER Filed July 17, 1959 2 Sheets-Sheet 2 INVEIYfdRHear-ice DORVAL ATTORNEYS United States Patent ENCLOSED GLASS HOLDERMaurice Dorval, 120 Pere Arnaud, Quebec, Quebec 8, Canada Filed 'July17, 1959, Ser. No. 827,915 3 Claims. (Cl. 312-320 is completely enclosedand thus prevents dust and other foreign matter from reaching the glassto thereby keep the glass in spotless condition, for hygienic purposes.

The glass holder in accordance with the invention is formed of twohalf-cylinders which are rotatable with respect to each other so that inone position they overlap to define a front opening for removal of theglass and in the other position the two half-cylinders define acylindrical enclosure which is closed at the top by a suitable cover.

According to a further specific feature of the invention the cover is soarranged that rotation of one of the halfcylinders to open positionautomatically lifts the cover, thus facilitating removal of the glass.

An embodiment of the invention is illustrated in the accompanyingdrawings in which:

Figure l is a front elevation of the holder;

' Figure 2 is a side elevation;

Figure 3 is a rear elevation;

Figure 4 is a top plan view;

Figure 5 is a perspective exploded view;

Figure 6 is a perspective view of a wall bracket for securing the holderto a Wall;

Figure 7 is a section of the holder on line 7--7 of Figure 1; and

Figure 8 is a section of the holder on line 8-8 of Figure 1 showing theholder in open position.

Referring to Figure 5, the holder comprises a rear plate 10 with a pairof side plates 11 to which are connected cylindrical walls 12,concentric with and disposed at the edge of a round base plate 13. Parts10 to 13 form an integral unit which may be moulded in a single piece ofsuitable plastic material.

A separate integral unit of the holder comprises a semicylindrical wall14 disposed at the edge of a second plate 15. The holder furthercomprises, as a separate piece, a cover 16.

As shown more particularly in Figures 3, 6 and 8, the rear plate 10 isformed with a trapezoidal recess '17 into which extend projections 18. Atrapezoidal bracket 19 is screwed to the wall and the recess 17 isslipped over the bracket 19 with the projections 18 engaging the bracketfor the purpose of securing the holder to a wall. This arrangement is,however, only given by way of example and any other conventionalfastening means may be employed.

The support plate 13 has in its centre a hole 20, Figure 5, adapted toreceive a short bearing shaft 21, flattened at 22, to form a handle.Thereby the unit comprising plate and wall 14 can be rotated on the unit10-13 to form either an enclosed space defined by walls 12 and 14, asshown in Figure 2, or, by grasping the handle portion 22 and rotatingthe unit through 180", an open space from which the glass 23, Figure 8,can be removed. In

the latter position the wall 14 generally overlaps the walls 12. Wall 14and plate 15 must, ofcourse, be of slightly smaller diameter than plate13 and walls 12.

The cover 16 comprises a substantially round portion overlying the spacedefined by walls 12 and 14 and a generally rectangular appendage fromwhich project on either side pins 24 which are adapted to be received bya pair of slots 25 in the side plates 11.

As best shown in Figure 8 the top edge 26 of wall 14 is slightlyupwardly convex and is adapted upon rotation to engage the bottomsurface of the cover 16 and to lift the same by pivoting it about pins24. The slots 25 are inclined forwardly at an angle of approximately 45so that, when the edge 26 engages the cover 16, it exerts on pins 24 aforce transverse to the longitudinal plane of the slots 25; thispreventing the pins 24 from travelling upwardly in the slots. Thearrangement is such that, as the holder is opened by rotating theassembly of wall 14 and plate 15, the cover 16 is lifted automaticallyto make it easier to remove the glass. slots 25 make it possible toremove the cover 16 without any trouble, for cleaning purposes.

As shown in Figure 5, the free edge of the plate 15 is provided with alip 27, for greater safety. With reference to Figure 5 and Figure 8, itwill be seen that the cover 16 has its bottom face 28 upwardly inclinedso that in closed position it accommodates the convex edge 26 and liesin a substantially horizontal position. The cover 16 is also providedwith a lip 29 which in the closed position overlaps the wall 14.

It can be seen from the foregoing description of the holder inaccordance with the invention that the structure is simple tomanufacture and easy and convenient to operate. It is noted that openingand closing of the holder requires the use of only one hand.

The embodiment of the invention which has been illustrated and describedis given merely by way of example and various modifications are possiblewithin the scope of the appended claims.

I claim:

1. A glass holder comprising a pair of generally semicylindrical walls,one of which is fixed and the other of which is rotatable coaxially withrespect to said one wall, cover means pivotally mounted on said one walland means on said other well adapted to raise said cover means as saidother wall is brought to overlapping position with respect to said onewall.

2. A glass holder comprising a pair of generally semicylindrical walls,one of which is fixed and the other of which is rotatable coaxially withrespect to said one wall, cover means-pivotally mounted on said onewall, said other wall having a convex top edge which engages and raisessaid cover means as said other wall is brought to overlapping positionwith respect to said one wall.

3. A glass holder comprising a pair of generally semicylindrical walls,one of which is fixed and the other of which is rotatable coaxially withrespect to said one wall, support means fixed to said one wall, a slotin each said support means, a cover having a pair of pins insertable insaid slots to pivotally mount said cover, said other wall having its topedge upwardly convex to engage said cover, said, slots being inclinedtoward the other wall at an angle such that said top edge exerts throughsaid cover on said pins a force directed transversely'of thelongitudinally plane of said slots to thereby raise said cover as saidother wall is brought to overlapping relation with respect to said onewall.
